OIL VAPORIZING, MIXING, AND DELIVERING DEVICE.

Specification of Letters Patent.

Patented Jan. 28,1919.

Application filed December 31, 1917. Serial No. 209,741.

To all whom it may concern:

Be it known that I, ARTHUR G. BECKWITH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oil Vaporizing, Mixing, and Delivering Devices, of which the following is a description.

My invention belongs to that general class of devices for vaporizing, mixing and delivering oil or the like to where desired. The same is particularly intended for use on steam locomotive engine service, but can be used in any steam engine service or wherever the same may be desired or found applicable. The invention has among its objects the production of a device of the kind described that is simple, convenient, compact, durable,

eflicient, and satisfactory. It has particularly as an object the production of a device'thatwill thoroughly vaporize and mix the oil or lubricant with the desired volume of steam, air or other fluid, and feed or deliver the same in the desired volumes at one or more desired points, for example on a locomotive engine or the like. It might be arranged to deliver the vapor into the steam chest and cylinder, or into a drifting valve or its steam pipe, etc. Many other objects, advantages and uses of the device will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Figure 1 is a sectional view through the preferred form of my device;

Fig. 2 is a sectional view taken substantially on line 22 of Fig. 1, and

Fig. 3 is a sectional view taken substantially on line 33 of Fig. 1.,

Referring to the drawings, 1 represents a casing or shell of suitable material and the desired size and shape, the shape being preferably as shown, surrounded by an outer jacket or shell 2, spaced therefrom so as to provide a space 3. The jacket 2 may be connected to the inner shell at the bottom, as shown, and to the top by means of the ribs or parts 4:, spaced around the same, there being, however, inlet spaces for the admission of fluid to the space 3, in the top, as will be seen by referring to Fig. 3. One end, preferably the upper end, of the casing l is extended as at 5, a shoulder 6 being provided about the extension 5. I have shown a stud 7 arranged at one side, by means of which the device may be supported or secured in place, if desired. The casing is also provided with a transverse partition or shelf 8, preferably near the bottom, dividing the easing into an upper chamber 9, and a lower chamber 10. \Vithin chamber 9 and supported by the shelf 8, is placed steel wool, coiled wire, or the equivalent, which serves to bafiie or restrict and retard the ready flow of oil through the chamber, but at the same time will permit a substantially free passage for the steam. Any equivalent baffling means may obviously be employed, that mentioned, however, being simple and ef-' ficient. I have shown a small outlet or drain opening 11 from the chamber 10, and a similar outlet or drain 12 from the chamber 3, these being more fully referred to hereinafter.

The extended part 5 is open at the top or is tubular, and is also provided with openings 16 of the desired size, shape, and number through the side walls. Mounted on the casing about the extension 5 is a chambered member 17, the chamber 18 therein being formed so as to surround the part 5 and connect with the opposite openings 16 and the jacket space 3. Part 17 is formed with one or more extending parts 19 provided with an inlet 20, the parts '2122 constituting a union for connecting extension 19 with a suitable source of steam or other vapor supply. Part 17 is maintained in place firmly against the shoulder 6 by a tubular part or nut 23, which may be provided with the union parts 23, 23", for connecting the device with the lubricator, as for example a hydrostatic lubricator. I may mention, however, that the lubricator itself forms no part of the present invention, and I wish to be understood by the term lubricator as includmg any lubricator or equivalent device suitable for the purpose. While I have not shown packing material between the parts, obviously any suitable packing may be used, the use of packing being well known in the art for preventing the leakage of steam, etc. If the parts shown, however, are properly tending part 26.

7 after.

finished and fitted, a tight joint may be obtained in many cases Without requiring additional packing.

Arranged at the bottom of the device is a tubular or chambered part 24:, having a chamber 25 and extending part 26, the part 26 projecting into the inner shell or casing above the bottom thereof, the upper end of the same beveled 0r brought to an edge 27 as shown in the preferred construction. A part 28 is arranged within the casing, and the same is shown being carried by the ex- Part 28 is formed with one or more openings 29 in the top, and with one or more openings 30 in the sides, and the same is preferably constructed so that the top face of the same is substantially level or even with the cross partition or shelf 8. The part 24 is provided with one or more outlet holes or openings 31 near the bottom of the chamber. On the projecting or depending end of part at is arranged a part 32, the same being chambered as at 33, and is retained in place by the nut 3-4, or equivalent means for the purpose. Part 32 is formed with one or more (as shown two) extending parts 35, which are tubular and communicate with the chamber 33. The parts 35 may be connected with the desired parts to be lubricated in any suitable manner. I have shown, however, the union parts 36 and 37. I have also shown the members 38, which may be arranged in part 35, the same being Venturi tubes or chokes, the bore being tapered as at 39 so that the outlet or duct 40 through which the fluid passes from the chamber 33 to the pipe or part 36 is reduced, the purpose of this being more fully explained here- In some cases one extension 35 will be suflicient for the purpose, while in other cases three or four of the extensions 35 would be necessary or desirable, in order that one of my devices might be arranged to deliver the oil after vaporizing and mixing, to several points.

Referring to Fig. 1, I have shown a pet cook 42 arranged at the drain outlet 11, and a drain pipe 45 connected with the drain outlet 12. Pipe l5 may be extended to where desired. As shown, it is connected to the casing or shell by a union consistingof the parts 4H6, and a choke 47, having a restricted outlet 48, may be provided if desired.

The installation and operation of the device may be briefly described as follows: It may be assumed for purposes of explanation that the same is to be used upon a steam locomotive engine or the like, and in practice the device is installed or located as close to theplace or places of delivery as possible, for'example near the steam chest. This location is preferred in order to have as short delivery device as possible, but when so installed. the same is exposed to the weather. The union or coupling pipe 23 is connected to a hydrostatic or other desired type of lubricator, so that oil or lubricant may enter the casing. The part 21 is connected to an independent steam pipe ar ranged to furnish steam at as near boiler pressure as possible, and in sufficient volume to supply the delivery pipes without much reduction in pressure. In practice it is preferred to connect the independent steam pipe (not shown) to a steam dome or other high point of the boiler. The steam entering through this pipe enters the casing, a portion passing from the chamber 18 through the openings 16, and into the chamber 9, while a portion of the same passes into the jacket space or chamber 3. The steam entering the chamber "9 vaporizes and mixes the oil with it, and forces a flow of the lubricant from the same from the delivery pipes 36 to where desired. The ba'fiiing means, such as steel wool, wire, or the equiv alent, bafi'ies and restricts or retards the ready flow of the oil through the chamber, but does not retard the passage of the steam or vapor to any appreciable extent. The oil is scattered or spread on the baffle so that the steam comes into contact with a large surface, thus vaporizing and mixing the oil with the steam. Some steam may be condensed and flow into the chamber 10. The greater portion of the vaporized oil and steam, however, passes through the openings 29 down through the tubular'chamber 25, out through the openings 31, and finally through pipes 36 to the desired point or points, for example, the'steam chest, cylinder and the drifting valve or the like. The level of the water in chamber'lO is determined by the top edge 27 on the part 26, and the same is maintained by the steam as it condenses. The purpose of'the trap or chamber 10 in addition to collecting the Water, is to collect upon the surface of the condensed steam such oil as is passed through the chamber 9, and is not completely vaporized or mixed with the steam. Someof this oil will then be vaporized-and mixedby the steam coming in contact with it, and the balance will flow into the part 24L, and out through the delivery ports, as the trap is continually flushed by the condensed steam entering into it. The trap isof importance, as it provides a final breaking up and'delivery of all oil that has not been vaporized or mixed with the steam in its passage through chamber 9.

The purposes of the drain. ll-and pet cock 42 are to empty the chamber for cleaning, and to prevent freezing when the engine is not in use. Obviously, the various pa'rts'to be lubricated may not require the same amount of lubrication. The members or chokes 38 may be varied in size as desired,

the same depending upon the number of deliveries and the volume of the mixed lubricant to be delivered by each, and they should not be so large as to materially reduce the pressure in the Vessel. For example, where a delivery is into a steam chest, cylinder or drifting valve, or its steam pipe, the steam chest chokes may be large, owing'to the large volume of steam that the delivered product must mix with. The cylinder choke may be considerably smaller, due to'the volume of steam in the cylinder being lessand having the benefit of the steam chest delivery. The drifting valve choke could be smaller still, as it would only have to lubricate the drifting valve and mix with the steam used in drifting, as both the steam chest and cylinder deliver the oil at this time. The several chokes restrict the delivery to the extent that boiler pressure or nearly boiler pressure will be maintained at all times within the vessel. This is of importance, for if the steam chest or other pressure at the delivery point exceeded the pressure in the chamber 9, the flow of steam would be from the steam chest into the chamber, and the device would fail. The steam chest pressure is continually changing, and it is impossible with an engine running to use and maintain boiler pressure in the steam chest, but it is possible to use and maintain very nearly boiler pressure in my device, so that a flow from the pipes into the steam chest and other delivery places is at all times insured.

The purpose of the steam jacket or space 3 is to protect the inner chamber 9 against the influence of cold from the outside, which would lower the temperature within the device. It'thereby assists in vaporizing and mixing the oil with the steam, and assists the independent steam pipe to maintain as high a pressure as possible by maintaining a high temperature about the inner shell 1. The chamber or space is provided with an open drain, the size of which may be regulated by the choke 47, or its'equivalent, having the restricted opening 48. This drain may be connected from the chamber to the main exhaust passage of the engine, and is intended to take care of all condensation in the chamber so that the same at all times is filled with live steam, thereby maintaining a high temperature. It will be noted that the parts 17 and 32 may be adjusted as desired, so that the intake or delivery pipe or pipes may extend as desired. Owing to the groove or recess 33 in member 32, the openings 31 are at all times open to the discharge outlets.

From the preceding it will be seen that my device consists of an oil vaporizing mixing and delivering apparatus, by means of which the oil or lubricant is carried from the lubri cater, vaporized, mixed and delivered in the desired volume or volumes to the one or more desired points.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.
